Tucked in behind Dorset's famous Chesil Beach is a unique and beautiful place - the Fleet Lagoon. Martha Kearney explores a thousand year history of human guardianship of birds on the lagoon. On the way she gets a close-up view of little tern dating platforms on the Fleet itself, learns why the swans of the ancient Abbotsbury Swannery are much safer now and who they hate the most, and - of course - learns to build a nest.

Contributors include:

Angela Thomas - Assistant Warden, Chesil and Fleet Nature Reserve Chris Goding - RSPB Project Officer & Assistant Warden, Chesil Little Tern Recovery Project Steve Groves - Swanherd, Abbotsbury Swannery
